Mobility big data analysis and visualization (Invited talk)

Abstract

Transportation systems in mega-cities play a very important role in social and economic activities. Especially in Japan, the Tokyo city is strongly required to increase resiliency and safety of its transportation systems, because of the 2020 Olympic games and big earthquakes predicted to occur. Our research group is trying to address those challenges utilizing mobility big data. We have been archiving several mobility data sets, such as smart card data and vehicle recorder data, and developed platforms for processing, analyzing, and visualizing them. In this paper I briefly introduce our analysis and visualization of passenger flows in public transportation systems and behaviors of vehicle drivers.
